Assessing pain in the elderly.

OBJECTIVE: Summarize practical strategies for recognizing and assessing pain in the long-term care population, particularly for cognitively impaired residents. DATA SOURCES: Live symposium presentation based on clinical practice and research and current clinical guidelines. CONCLUSIONS: Pain that is under-recognized and undertreated can result in significant physical and social disability in the elderly long-term care population. Proper assessment of pain is needed to diagnose and determine an appropriate and individualized treatment plan for each resident. Consultant pharmacists play critical roles as medication experts and members of the long-term care interdisciplinary team that can assist other team members in the assessment, treatment, and management of pain in older adults.

The self-administered 24-item geriatric pain measure (GPM-24-SA): psychometric properties in three European populations of community-dwelling older adults.

OBJECTIVE: To explore the feasibility and psychometric properties of a self-administered version of the 24-item Geriatric Pain Measure (GPM-24-SA). DESIGN: Secondary analysis of baseline data from the Prevention in Older People-Assessment in Generalists' practices trial, an international multi-center study of a health-risk appraisal system. PARTICIPANTS: One thousand seventy-two community dwelling nondisabled older adults self-reporting pain from London, UK; Hamburg, Germany; and Solothurn, Switzerland. OUTCOME MEASURES: GPM-24-SA as part of a multidimensional Health Risk Appraisal Questionnaire including self-reported demographic and health-related information. RESULTS: Among the 1,072 subjects, 655 had complete GPM-24-SA data, 404 had 30% missing GPM-24-SA data. In psychometric analyses across the three European populations with complete GPM-24-SA data, the measure exhibited stable internal consistency, good convergent, divergent and discriminant validity, and produced stable pain measurements. However, factor analysis indicated differences in the GPM-24-SA across sites with discrepancies mainly related to items of a single subscale that failed to load appropriately. Analyses including imputation for subjects with

Geriatric Pain Measure short form: development and initial evaluation.

OBJECTIVES: To develop and evaluate a short form of the 24-item Geriatric Pain Measure (GPM) for use in community-dwelling older adults. DESIGN: Derivation and validation of a 12-item version of the GPM in a European and an independent U.S. sample of community-dwelling older adults. SETTING: Three community-dwelling sites in London, United Kingdom; Hamburg, Germany; Solothurn, Switzerland; and two ambulatory geriatrics clinics in Los Angeles, California. PARTICIPANTS: European sample: 1,059 community-dwelling older persons from three sites (London, UK; Hamburg, Germany; Solothurn, Switzerland); validation sample: 50 persons from Los Angeles, California, ambulatory geriatric clinics. MEASUREMENTS: Multidimensional questionnaire including self-reported demographic and clinical information. RESULTS: Based on item-to-total scale correlations in the European sample, 11 of 24 GPM items were selected for inclusion in the short form. One additional item (pain-related sleep problems) was included based on clinical relevance. In the validation sample, the Cronbach alpha of GPM-12 was 0.92 (individual subscale range 0.77-0.92), and the Pearson correlation coefficient (r) between GPM-12 and the original GPM was 0.98. The correlation between the GPM-12 and the McGill Pain Questionnaire was 0.63 (P<.001), similar to the correlation between the original GPM and the McGill Pain Questionnaire (Pearson r=0.63; P<.001). Exploratory factor analysis indicated that the GPM-12 covers three subfactors (pain intensity, pain with ambulation, disengagement because of pain). CONCLUSION: The GPM-12 demonstrated good validity and reliability in these European and U.S. populations of older adults. Despite its brevity, the GPM-12 captures the multidimensional nature of pain in three subscales. The self-administered GPM-12 may be useful in the clinical assessment process and management of pain and in pain-related research in older persons.

Rheumatic diseases in the elderly: assessing chronic pain.

This article discusses the assessment of chronic pain in older patients. First, the epidemiology and impact of chronic pain in the elderly are addressed. Next, common barriers to pain assessment are reviewed. An effective approach to pain assessment in the older patient is described, including the important pearls of history-taking and the physical examination, as well as recommendations for the evaluation of functional status and psychosocial well-being. The article concludes with a review of multidimensional and unidimensional pain assessment tools, and a discussion of methods for pain assessment in the cognitively impaired.

Multidimensional attitudes of medical residents and geriatrics fellows toward older people.

OBJECTIVES: To examine dimensions of a validated instrument measuring geriatric attitudes of primary care residents and performances on these dimensions between residents and fellows. DESIGN: Cross-sectional and longitudinal studies. SETTING: An academic medical center. PARTICIPANTS: Two hundred thirty-eight primary care residents (n=177) and geriatrics fellows (n=61) participated in the study from 1995 to 2000. MEASUREMENTS: A 14-item, 5-point Likert scale previously validated for measuring primary care residents' attitudes toward older people and geriatric patient care was used. RESULTS: Factor analysis showed four dimensions of the scale, labeled Social Value, Medical Care (MC), Compassion (CP), and Resource Distribution, which demonstrated acceptable reliability. Both groups of subjects showed significantly (P<.001) positive (mean>3) attitudes across the dimensions and times, except for residents, who had near-neutral (mean=3) attitudes on MC. Residents' mean attitude scores on the overall scale and the MC and CP subscales were significantly (P<.001) lower than those of fellows over time. Residents and fellows showed different change patterns in attitudes over time. Residents' attitudes generally improved during the first 2 years of training, whereas fellows' attitudes declined slightly. Personal experience was a strong predictor of residents' attitudes toward older patients. Ethnicity, academic specialty, professional experience, and career interest in geriatrics were also associated with residents' attitude scores. CONCLUSION: The multidimensional analysis of the scale contributes to better understanding of medical trainees' attitudes and sheds light on educational interventions.

The management of pain in long-term care.

OBJECTIVE: The purpose of this paper is to present salient principles of pain management in nursing homes and other long-term care settings. METHODS: Review and author opinion. RESULTS: Pain is a common problem in nursing homes and other long-term care facilities. Often unrecognized and under-treated, pain is a major source of suffering and functional impairment. These patients present substantial barriers to pain assessment and management. Multiple concurrent disease processes, cognitive impairment and communication difficulties, and limited access to diagnostic technologies make assessment more difficult. Multiple medications, altered physiology and pharmacology and limited access to a variety of drug and non-drug interventions make treatment strategies more difficult to implement. DISCUSSION: Clinicians who care for patients receiving long-term care services must help establish a treatment plan that is reasonable given the limited resources and skills available in nursing homes and other long-term care facilities. Medication regimens should be simplified as much as possible. Contingency plans for pain management must be anticipated and made available so that delays do not occur during medication changes or dosage adjustments. Long-term care facilities need substantial support from physicians and other pain experts for education to continuously update their skills and knowledge. As the need for health systems for frail elderly persons continues to grow, it is important to provide comfort and effective pain control appropriate for these new settings.

Development and validation of a geriatric knowledge test for medical students.

OBJECTIVES: To assesses the reliability and validity of a geriatrics knowledge test designed for medical students. DESIGN: Cross-sectional studies. SETTING: An academic medical center. PARTICIPANTS: A total of 343 (86% of those sampled) medical students participated in the initial study, including 137 (76%) first-year, 163 (96%) third-year, and 43 (86% of those sampled) fourth-year students in the 2000-2001 academic year. To cross-validate the instrument, another 165 (92%) third-year and 137 (76%) first-year students participated in the study in the 2001-2002 academic year. MEASUREMENTS: An 18-item geriatrics knowledge test was developed. The items were selected from a pool of 23 items. An established instrument assessing the clinical skills of medical students was included in the validation procedure. RESULTS: The instrument demonstrated good reliability (Cronbach alpha=0.80) and known-groups and concurrent validity. Geriatrics knowledge scores increased progressively with the higher level of medical training (mean percentage correct=31.3, 65.3, and 66.5 for the first-year, third-year, and fourth-year classes, respectively, P<.001). A significant (P<.01) relationship was found between the third-year students' geriatrics knowledge and their clinical skills. Similar results, except the relationship between knowledge and clinical skills, were found in the cross-validation study, supporting the reliability and known-groups validity of the test. CONCLUSION: The 18-item geriatrics knowledge test demonstrated sound reliability and validity. The average scores of the student groups indicated substantial room for growth. The relationship between geriatrics knowledge and overall clinical skills needs further investigation.

The quality of medical care provided to vulnerable older patients with chronic pain.

OBJECTIVES: To assess the quality of chronic pain care provided to vulnerable older persons. DESIGN: Observational study evaluating 11 process-of-care quality indicators using medical records and interviews with patients or proxies covering care received from July 1998 through July 1999. SETTING: Two senior managed care plans. PARTICIPANTS: A total of 372 older patients at increased risk of functional decline or death identified by interview of a random sample of community dwellers aged 65 and older enrolled in these managed-care plans. MEASUREMENTS: Percentage of quality indicators satisfied for patients with chronic pain. RESULTS: Fewer than 40% of vulnerable patients reported having been screened for pain over a 2-year period. One hundred twenty-three patients (33%) had medical record documentation of a new episode of chronic pain during a 13-month period, including 18 presentations for headache, 66 for back pain, and 68 for joint pain. Two or more history elements relevant to the presenting pain complaint were documented for 39% of patients, and at least one relevant physical examination element was documented for 68% of patients. Treatment was offered to 86% of patients, but follow-up occurred in only 66%. Eleven of 18 patients prescribed opioids reported being offered a bowel regimen, and 10% of patients prescribed noncyclooxygenase-selective nonsteroidal antiinflammatory medications received appropriate attention to potential gastrointestinal toxicity. CONCLUSION: Chronic pain management in older vulnerable patients is inadequate. Improvement is needed in screening, clinical evaluation, follow-up, and attention to potential toxicities of therapy.

Effects of a controlled exercise trial on pain in nursing home residents.

OBJECTIVES: To report preliminary data relevant to the effects of an exercise and toileting intervention on pain among incontinent nursing home (NH) residents. DESIGN: A randomized controlled intervention trial. SETTING AND PARTICIPANTS: Fifty-one incontinent residents in one skilled NH. INTERVENTION: The intervention was implemented by research staff for a total of 4 times a day (every 2 hours), 5 days a week, for 32 weeks. Residents were provided with incontinence care and assistance to either walk or, if nonambulatory, wheel their chairs, and to repeat sit-to-stand movements. MEASUREMENTS: Pain was measured in two ways at baseline and again at 32 weeks: (1) a count of the number of verbal expressions and pain behaviors during a standardized physical performance assessment; and (2) a modified Geriatric Pain Measure administered in a one-on-one interview format. RESULTS: There were significant differences between intervention and control groups on all physical performance measures over time, with the intervention group remaining stable and the control group showing a significant decline in sit-to-stand, walking, and wheelchair propulsion endurance. Both groups showed mild to moderate pain at baseline according to each of the two pain measures, while there were no significant changes in pain reports between groups over time based on either measure. There was, however, a trend for pain to increase in the intervention group. CONCLUSIONS: No significant changes in pain reports were attributable to exercise despite significant improvements in physical performance. In fact, there was a tendency for pain reports to increase with exercise. These preliminary findings suggest that exercise alone may be ineffective for pain management among incontinent NH residents. Care providers should consider that exercise to improve physical function may increase pain symptoms, requiring preemptive analgesia, other pain control strategies, or modified exercise techniques for this frail segment of the NH population.
